Trenbolone (Tren): Trenbolone with the shorter Acetate ester attached, was originally developed to put weight on cattle and was manufactured and circulated under the name – Finaplix. This was a small implanted pellet under the skin and released the hormone at varied rates. Finaplex was given to cattle to put a large amount of muscle tissue on the said animal and that’s exactly what it did in a short time frame. When given to humans this is also what happened and why Trenbolone has been given the gold medal as the best mass gaining anabolic steroid, whilst simultaneously incinerating excess and unwanted body fat. Scientists attached the longer acting – Enanthate ester to Trenbolone and extended its half-life by around 10 days, compared to Acetate which is 3 days. Other than it being used to put more lean muscle mass on animals, it has never been legalised by the FDA for human use in any country.

Performance Enhancement: Trenbolone is 5x more anabolic and androgenic than testosterone itself, with a rating of 500:500. This means a lot of things that will be discussed on this site, but in regards to performance enhancement, it means this anabolic steroid is a potent mass builder and fat burner. We have already discussed its ability to add muscle to cattle and the same can be said when given to humans. It does this by a number of mechanisms, such as increasing protein synthesis, nitrogen retention and its effects on IGF-1 (Insulin Like Growth Factor). It increases serum IGF-1 more so than any other steroid and increases the muscles sensitivity to IGF-1. It also binds very strongly to the androgen receptor (AR) again enhancing muscle tissue accrual. Because of its potent effects on muscle gain, it will enhance performance (speed, agility) dramatically. This is an advantage in contact sports, athletics, bodybuilding shows and due to its positive effects on strength, is a good choice for strength athletes.

Stacks well with: Trenbolone is a very inhibitive compound to endogenous testosterone production. It has a dramatic suppressive effects on hormones responsible for well-being, sexual function, confidence, energy levels and erectile function. That means it shouldn’t be a steroid used alone due to losing those previously stated positive effects. It has to be stacked with a testosterone base, such as Testosterone Enanthate or Sustanon 250. A base or backbone of testosterone is suggested but in the very rare few Trenbolone alone is sufficient as it can increase libido in some.

As a mass agent it can be stacked with oral steroids predominantly used for bulking, such as Dianabol and Anadrol. As well as secondary anabolics (alongside testosterone base) such as Deca-Durabolin. As a cutting anabolic steroid, it can be used very effectively with Winstrol (Stanozolol), Masteron and Anavar. Adding compounds and stacking them causes synergy effects multiplying the positive effects of all the anabolic steroids used. Stacking is the most effective form of cycling but care needs to be taken choosing which compounds to run with each other whilst limiting and controlling side effects.

Pricing: Tren is one of the most expensive anabolic steroids available. This is due to the raw material being expensive to manufacture. A 10ml bottle of Trenbolone Acetate at 100mg/ml is around $40-80. Trenbolone Enanthate is priced similarly at $40-90 for the same amount of 10ml. But that’s not the most expensive form of Trenbolone, that’s where Parabolan (Trenbolone Hexahydrobenzylcarbonate) which is one of the most expensive anabolic steroids per gram compared to any other. For 10ml of quality Tren Hex, you talking around $60-100+.
